DESCRIPTION

29       The  makedevice()  function  creates  a  device number from a major and
30       minor device number. makedevice() should be used to create device  num‐
31       bers  so the driver will port easily to releases that treat device num‐
32       bers differently.
33

RETURN VALUES

35       The device number, containing both the major number and the minor  num‐
36       ber,  is  returned. No validation of the major or minor numbers is per‐
37       formed.

CONTEXT

40       The makedevice() function can be called from user, interrupt, or kernel
41       context.
